App.xaml.cs uses buggy code to submit to the clipboard

What steps will reproduce the problem?
1. In a debugger that disassembles C#, step into Marshal.StringToHGlobalUni.
2. Read the source code and notice the LocalAlloc with LMEM_FIXED.
3. Read the docs for SetClipbaordData
4. Scream
5. Read the comment here on StackOverflow:

What is the expected output? What do you see instead?

The expected output is to not corrupt the system memory.  Instead you see that 
the code may crash.

What version of the product are you using? On what operating system?

Not using the software.  Just googled for this code pattern after having 
problems with it.  Here's the version I spotted it in:

Please provide any additional information below.
